Study of the Inhibition Effect of Carbendazim Towards Carbon Steel Corrosion in 0.50M HCl Solutions

The inhibition effect of sodium glutarate towards corrosion of carbon steel in neutral 0.02 M NaCl solution was investigated with potentiodynamic polarization and electrochemical impedance measurements. Results of electrochemical measurements revealed a poor inhibitive action for low concentrations (1 mM and 5 mM) and a significant improvement in efficiency for concentrations of 32 mM or higher. The protective film exhibited excellent stability in the temperature range 22°C–55°C. Full chemical passivation was accomplished and analysis of the impedance spectra for the high concentrations of glutarate was consistent with the inhibition mechanism which assumes that the carboxylates support the passivation of carbon steel in aerated solutions by plugging the defect sites and that the passivation process is enhanced by adsorption of the carboxylates on the oxide-covered surface. Such mechanism was confirmed by the XPS analysis.

Loss Method

This paper uses a metal hung weight loss method, acidic ionic liquid desulfurizer as the media, by adding different inhibitor (Polyethylene Glycol, SDBS, Functional ionic liquids), contrast to carbon steel corrosion in the absence of inhibitor, understanding of their respective inhibition effect. In the experiment, the carbon steel material, different kinds and concentrations of the inhibitor in the medium, the corrosion rate measured by weight loss method. Contrast to the blank experiment the inhibition rate can be calculated. The experiment proved that the inhibition effect of several inhibitor at room temperature, and calculate their respective optimal concentration. The experiment also investigated the compound of several corrosion inhibition synergies, confirm the good corrosion inhibiting effect of polyethylene Glycol and SDBS complex, the inhibition rate reached 69.2%.Excellent inhibition effect of the ionic liquid corrosion inhibitor and the inhibition rate reached 88.3%, showing a clear advantage.
